Attack No. 1 (アタックNo.1,Atakku Nanbā Wan) is a Japanesemanga series by Chikako Urano. It also became the first televised female sports anime series in the shōjo category.

The anime is an adaptation of Chikako Urano's 1968 volleyball manga serialized in Weekly Margaret Magazine under the same name.[1] Chikako was considered one of the founders of shōjo anime.[2] And the series was introduced not only to push the older female manga fan base (as opposed to the significantly younger audience for magical girl series such as Sally, the Witch) into the anime mainstream, but also capitalizes on the boom of the gold medal Japanese women's volleyball team in the 1964 Olympics.[3] The show did stand out in an era dominated by shōnen adventures and sci-fi anime, and was well received in the anime-friendly television markets of France (as "Les Attaquantes"), Italy, (where it was originally retitled "Quella magnifica dozzina" and later "Mimì e la nazionale di pallavolo", where Kozue was renamed Mimì) and Germany (where it was retitled as "Mila Superstar", where Kozue was renamed Mila). The name Mila came from the immensely popular Italian version of 1984's Attacker You!, in which the main character, You Hazuki, was renamed Mila.

A direct sequel was also released in manga format called Shin Attack No.1 (New Attack No.1) in 1976, but it was short-lived. The sequel was later redrawn between 2004 and 2005 in a new style by Kanon Ozawa.

The story is about a high school girl, Kozue Ayuhara, who transferred to Fujimi Academy and tried out for the school volleyball team. She develops a friendship with her teammate Midori Hayakawa, and her talents impress coach Hongō more and more each day. Though she showcases extraordinary volleyball skills, she makes enemies with Katsuragi, the star of the current team. Kozue discovers that being at the top would bring stress, incompatibilities and other dilemmas into her life. Her high expectations of becoming the best volleyball player in the school, Japan and eventually the world, set the tone for the drama to follow.

Ayuhara is a second year who moved away from Tokyo to a rural junior high school to rehabilitate an illness (which makes her quit sports). After a run-in with other students in the school, she returns to sports (Volleyball), and quickly becomes the leader of the team. Kozue initially begins associating with a group of "delinquents" in the school. The volleyball team members dislike this, and Kozue makes her own team and challenges the real volleyball team to her own. By a slim margin, Kozue's team wins, allowing some of the "delinquent" girls to integrate into the volleyball club, expanding it. From then on, Kozue becomes the captain of Fujimi Middle School's volleyball team.

Hayakawa was born into a wealthy family. She joins the volleyball team and begins playing selfishly in the team, demanding that she deserves to be captain due to her great skills. After some strong persuasion and fighting with Kozue, she becomes #2 on the team, and a friend to Kozue.

One of the Japan Best Twelve, she initially acts quite hostile towards Kozue and the other girls in the Best Twelve. No one is very aware of her, but it is revealed that her team never progressed very far in championships, because, according to Sanjou, she was the only good player on her team. It is revealed that she hates Kozue because of her love for volleyball; Michiru's beloved brother (who was also her only family) was in the volleyball club in college but went missing as a result of an apparent accident in the volleyball club. She stabs the volleyball he gave her in a fit of histeria, but she keeps the deflated ball with her as a memento of him. Although she hates volleyball as a result of the trauma of losing her only family, she uses the sport as a way to "get revenge" for losing her brother.

Shellenina is from the Soviet Union and is Kozue's rival. They first meet in their first match together after Fujimi wins the All-Japan championship. Kozue's team ends up losing, due to stress and anxiety from Kozue. Shellenina demnads they fight again when Kozue is at her best.

Inokuma was a friend of Hongo's during university. Hongo was on the baseball team and Inokuma the volleyball team. After the death of his father, he goes crazy and dedicates himself entirely to volleyball. He trains too hard, however, and injures his right wrist beyond repair, rendering him unable to play volleyball ever again. He is seen again in the current timeline of the series during the second National Japan Junior Volleyball competition. Hongo does not initially recognize him, but on the train ride back from Tokyo, he recognizes Inokuma. While they catch up, it is learned that Inokuma led the girls South Korean volleyball team to being second in the world. Then, he coaches Kozue and Midori when they are selected in the best twelve to represent Japan's junior volleyball team. He appears even more demonic and harsh than Hongo initially did.

The story is very similar to the original, but it has a few differences.

At the beginning of the manga series, Midori Hayakawa didn't like Kozue that much because Kozue was really good at volleyball (but they soon became best friends), but in the 2005 drama, Midori has bigger issues with Kozue. First of all, Midori was better at volleyball than Kozue at the start of this drama, and was very jealous when Kozue got called to come and play for Japan's national team (although at this point they didn't play any matches, but trained to become stronger). Secondly, Midori has a huge crush on Ichinose Tsutomu-kun. Midori had known Tsutomu-kun since she was very young, and when she found out that he liked Kozue, she was extremely jealous of Kozue. But when Tsutomu-kun died while saving a young boy, Midori's jealousy sort of evaporated. Thirdly, when Kozue helped some girls who were in her volleyball team, Fujimi, from a drunken man, she became popular, and got the No. 1 tracksuit for Fujimi, Midori was very jealous, so she didn't tell Kozue that Kozue had been taken out of Japan's volleyball team because, replacing her, Midori had been called to play for Japan. Despite all this jealousy from Midori, Kozue and she are best friends, and in the end get to play together for Japan, as Kozue is called back.

Another difference is that Kozue injures her leg very badly and has to have surgery, but recovers fully.
Also, in this drama, it doesn't reveal if Japan won worldwide, since it ends where Japan are playing Brazil

In 1977 Fumio Kurokawa, Eiji Okabe and writer Haruya Yamazaki helmed Attack on Tomorrow (based on a new story by Hana no Ko Lunlun creator Shiro Jinbo) for the Nippon Animation studio, but it didn't come close to matching the success of the original series.

In 1984 Kazuyuki Okaseko directed Attacker You! for the Knack animation studio; while not an official spinoff of Attack No. 1, Attacker You! invited the inevitable comparisons with the earlier series, although the latter was heavier on comedic elements. In addition, the screenwriters for the Italian version created a relationship between that series and Attack No. 1 that was not present in the original Japanese: they rewrote You Hazuki (Mila) as a cousin of Kozue, who was renamed "Mimi Ayuhara" in the Italian dub of Attack No. 1. This Voltron-style reworking of the story of Attacker You! by the Italian dubbing staff carried over into the French and Spanish versions of the anime. To compound the confusion, the heroine of Attack on Tomorrow is named Mimi in both the Japanese and Italian versions (although she is renamed Virginie in the French version).

This series was practically responsible for the explosion of the shōjo subgenre from 1960s and on. It was originally screened in evening prime time with a ~20% viewership, and the record with its iconic opening theme, sung by Kumiko Oosugi, had about 700 thousand sales.[14] There were countless series that followed the same concept, but shifted the focus to different sports. Ace wo Nerae! for tennis, Yawara! A Fashionable Judo Girl for judo are just some examples of series that appeared in the decades after the fading of this series.

The show has received numerous awards. On September 23, 2005 it was voted "TV Asahi Top Anime" placing 61 out of 100. On October 13, 2006 it was voted "Japanese Favorite TV Anime" placing 9 out of 100 among celebrities.[15]

This show also had a profound impact not only for being a sport spirited (supokon) anime in Japan, but had a strong influence long after the series ended. Italian professional volleyball player, Francesca Piccinini, is one such example of someone inspired by the series.[16] (In Italy, the anime was shown on TV in the 1980s under the title Mimi e la nazionale della pallavolo. It was also known as Mila Superstar in Germany and other countries, Les Attaquantes in French, La Panda de Julia in Spanish and TAKKITAKKI in Uzbekistan.)

Kazuko Suzuki describes Attack No. 1 as an "innovation on the campus story", where a heroine would go to college and meet her future husband. She describes Kozue as "psychologically independent", as Kozue has realised that she must strive to create her own happiness and continues to strive on after her boyfriend's death.[17]
